1990 Prelude Si ALB Again
 

Engine: B21A1
Transmission: 5-speed
Mods: NONE - all stock

Thanks to everyone who responded to my initial question about my car. I
changed out the PCV valve, (Only $3.51 after tax) and unfortunately this
has done nothing to lessen the vast amounts of oil that disappear from
my car. Again, I don't think I have a leak, because there are never any
oil spots under my car when I park it for the night and come back the
next morning. The new record for oil consumption: 2 quarts in 3 days!!
Granted, in those 3 days I drove over 300 miles, but that's only 150
miles per quart! It doesn't stumble or falter at all, there is no blue
smoke at any RPM level (I've checked for this time and time again) and
the other day I clocked my 0-60 time at roughly 7.5 seconds. So, as you
can see, my car has plenty of power. So I throw my question again to
the wealth of Honda knowledge in this newsgroup:

Where is my oil going?

A guy I work with used to work for a Honda performance shop, and he said
that it could be possible that my compression rings are fine, but the
oil rings are shot. Is this possible? Could it still be the valves?
Is it possible for oil to leak only while the car is running and not
leak after it's shut off? I hope someone can throw me a clue because
I'm drowning here...in cases of oil... ;-)

Thanks again! :-)

If the oil is getting into the combustion chamber, you should be able
to see evidence of it on the spark plugs.
I have seen the oil ring problem. Have you owned the car long? bob

Into your combustion chamber. Your cat is trapping the smoke before it
gets out of the tailpipe.

Yep. More likely the rings are bad all around, though.

Modern motor oils combust very efficiently, so you're unlikely to see
oil deposits on the plugs unless your spark is weak.

A tip if you want to try this: With engine warm, pull your primary
oxygen sensor from its hole (before the cat, get it?). Start car, idle
it and rev it. If you've got a smoker, the smoke will pour out of the
sensor hole.

If you try this and there's NO smoke, then the mystery deepens...

Worn bearings can cause smoke as well. Excessive oil throwoff bombards
the underside of the pistons, and the rings are unable to scrape it away
fast enough.



> Could it still be the valves?



Valve guide oil seal leaks are evident as a puff of smoke on startup,
before the cat has have a chance to warm up and start eating the smoke.



> Is it possible for oil to leak only while the car is running and not

Yes, but that usually causes a huge mess on the engine and many drips
when the car is stationary.

I have only owned it since this past August. The guy before that only
had it about 6 months. (He was an older gentleman who babied it to
death...probably never revved it above 3,000 RPM) The person before
that was supposedly the original owner, who obviously would have had it
for ~16 years. It has always used oil, but has been getting
progressively worse. The spark plugs I use are the Bosch +4's, so
supposedly it's the hottest spark you can get. ($6 each plug) I
haven't checked them recently, but when I first changed them after I
bought the car, the original plugs were stock NGK's that were worn, but
did not have any oil residue on them at all.

I thought that if your compression rings are bad that your horsepower
decreases. Is this correct?

Hmm...I've looked for blue smoke when cranking the car in the morning to
let it warm up, and I've never seen any blue smoke, just white smoke,
but that's to be expected on cold days, of course. ;-)

I checked the underside yesterday, and it's fairly clean. It has a
little bit of gunk build-up, but nothing that would warrant leaking 2
quarts every 3-4 days.

Update: I took my car to a Honda specialist who worked in a dealer's
shop for over 10 years and asked him what he thought. He said that it's
burning oil because of the design of the cylinder walls; they're made of
carbon-fiber which tears up piston rings and makes rebuilding the engine
practically impossible. (He mentioned a very bad experience with a car
like mine in the past, and actually declined to work on my car because
of this) My next question is, what other engines besides the B21A1
would fit in my car with the least possible amount of modification to
the body and/or engine mounts? Would an H22A fit, per chance? Or, if I
could find one, a B21A? (The Si-States engine; made only in Japan)

One final question: The mechanic said that I have a small chance of
making the oil consumption lessen drastically if I follow these steps:
1. On my next oil change, use synthetic oil and SeaFoam.
2. As soon as that gets the least bit dirty, change it, and use
synthetic oil again, but this time no SeaFoam.
3. When that gets dirty, change and go back to regular oil.
He said that doing so will "loosen up" the piston rings and possibly
cause them to create a better seal.

Does that hold water? I haven't heard of doing that before, but then
again I've never had a car go through oil this fast...

Thanks again to Bob & Tegger for your feedback! I really appreciate it!

Nope. I have a '91 Integra. B18A1. Has its own oil problems at the
moment. 283K miles and 1,800 miles per quart. Pretty high. This will
increase to 1,300 miles per quart in the summer.

Maybe. But _how much_ is your power affected? You CAN have excellent
power but high oil consumption.

You'd better make absolutely certain that "white" smoke isn't actually
"blue". It can be hard to tell from a distance.

You cannot really see that smoke while in the driver's seat. Have a
helper crank while you stand at the rear of the car and watch the
tailpipe.

If it's not dripping, then you're eating the oil. Your engine's gone
bad, my friend. Face up to it.

Why would you do that? What possible advantage would hot plugs
get you?

there's plenty of affordable "upgrade" jdm motors that you can
substitute. you could mess about with new rings, but it's not a
guaranteed fix and takes a lot of time and effort. you can sub in a new
motor in half a day if you know what you're doing.

those are just the earth electrodes - they're not the "hot" bit. all
they mean is that you are supposed to be able to do high mileage with
the average electrode gap not degrading too quickly. but in my
experience, bosch plugs aren't worth the effort, no matter /what/
whizzbangery they're supposed to have.

the best consumer grade plugs available are iridiums, imo. [ngk, denso]
but they don't affect oil consumption.

It has, and I expect Honda cars of the 1990 era to use some oil. Nearly
everyone I talk to that has owned a Honda that was in the late 80's to
early 90's have used oil. (Nothing near what mine does, granted, but
I've pretty much accepted the fact that a used Honda of this age is
probably going to use oil unless the engine has been rebuilt or replaced
quite recently) My 1990 Civic LX drank about a quart every 1000-1500
miles or so, and the engine in it came out of a like-model that had been
owned by an old lady who only drove it to and from the grocery store and
church for 12 years, putting only 75,000 miles on it.

I still don't regret buying the car because I have always wanted a
Prelude but could never find one that didn't have a salvage title. (I
never thought I'd find an Si-ALB with a clean title) I am very pleased
with the level of performance this car is able to dish out. I like not
having to downshift to 4th gear to go up a steep hill as I had to do
with my Civic. Also, the 2.5 second reduction in 0-60 time is nice as
well. ;-) (10 in Civic, 7.5 in Prelude) However, with what I know
now, I definitely would have negotiated a lower price, but as they say,
hind-sight is 20/20...

I saw the Bosch +4 plugs advertised and they seemed like a good
investment. ( http://www.autobarn.net/bosplat4spar.html ) But, if they
aren't making a difference, then needless to say I will go back to NGK
after these wear out.

He also said that if I keep driving it with it drinking that much oil it
will eventually burn the exhaust valves, totally ruining the engine. Is
that correct?

Which one would you suggest I upgrade to? Will an H22A fit my car?

He is a regular fount of misinformation. As long as you maintain the oil
level between the limits on the dipstick you won't have any problems there.
Burned valves are a possible consequence of misadjusting the valve
clearances. Of course, if you let the oil get too low burned valves will be
the least of your trouble, so check it regularly.

My '93 Accord was still just sipping oil at 150,000 miles when I unloaded it
last fall. Engine remained all original.

BTW, Bosch plugs are junk. Get rid of those and put OEM plugs in there.

it'll fit, but you may have to mess with motor mounts and driveshafts.
and electronics if you go vtec. do a google search for honda hybrids
and you'll find plenty of ricers that have done plenty of swaps like
this. personally, i'd go with a tamer swap to more recent b20. you can
get a b20b for $700 here:

put a hotter cam in that, and you could have a fun motor.

or you could go to this guy and see what he can do for you:
